Growth Hormone

Abbreviation: GH

Panel: Hormone Tests · All hormones tests

Typical adult reference range

Conventional units<10 ng/mL
SI units<10 ng/mL

Ranges vary between laboratories and methods — compare your result with the range printed on your own report.

What a high or low result can mean

High growth hormone: high values can be seen in acromegaly and transiently during sleep, exercise, and stress.

These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.

Good to know

Secreted in pulses, so a single random level is hard to interpret; IGF-1 is often used as a screening marker.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
